What is a Transceiver?

Question:

What is a Transceiver?

Answer:

An abbreviation of transmitter-receiver, the transceiver combines a transmission function and a reception function. Generally, the term "transceiver" brings to mind a wireless communication terminal, but in digital circuits, transceivers are also employed as bus transceivers to switch input and output of bidirectional buses , thereby enabling bus arbitration. The difference with a bus buffer is that the input and output of buffers are bidirectional and shared.
